scalene

Connects to multiple AI providers like OpenAI, Azure, and Ollama to generate code improvement suggestions directly in the profiling interface, making optimizations actionable.

Uses efficient sampling with typically 10-20% overhead, running orders of magnitude faster than many profilers while maintaining high accuracy.

Provides detailed CPU, memory, and GPU profiles per line of code, separating Python, native, and system time for precise bottleneck identification.

Automatically identifies lines responsible for likely memory leaks and reports copying volume, aiding in debugging memory-intensive applications.
